Abstract

An electrically conductive fluid distribution element for use in a fuel cell having a conductive non-metallic porous media having a surface with an electrically conductive metal deposited along one or more metallized regions. The metallized regions are arranged to contact a membrane electrode assembly (MEA) in a fuel cell assembly, and thus improve electrical conductance at contact regions between the MEA and the fluid distribution media. Methods of making such a fluid distribution element and operating fuel cell assemblies are also provided.
